Just a general question regarding the ACEs.
Currently, a pair of 6509s each with vss720s and an ACE.
Current layout (only one VIP right now, more to come very soon)
is very similar to diagram in cisco document ID 107400, configuring
ACE in routed mode with L7 policies. It seems to me that the design
in this document implies that ALL traffic to and from the real servers
(slb as well as non-slb) traverses the ACE.
My layout is as follows:
One vlan (call it vlan 100) is for VIPs and has L3/hsrp on the msfcs.
Other vlan (call it vlan 101) is for real servers and only exists at layer
2 on the 6509s. The alias IP on interface vlan 101 is the default gateway
for the real servers. I have a static route on the msfc for non-slb traffic and
other traffic directly to the real servers. Real servers are VMs.
The question I have is this - not all traffic that traverses the ACE is
load balance eligible, there will be pass-trhough traffic (non slb eligible)
that traverses the ACE. This does accomplish both forward and reverse
slb traffic traversing the ACE, but with non-slb traffic traversing the ACE,
is this scalable? I guess what I'm worried about paying a performance penalty
knowing that a lot of the traffic isn't slb eligible. I have no problem installing
a license for increased bandwidth.
Any responses/advice/comments are appreciated - chris
